.'*This invention-,relates 'tol for cultivators and has `for its object to vpijovide a comparatively simple and inexpensive'deviceby means ofl which tliebrdinary wheeled c ultivator may: be readily kconverted into. a lister lcorn cultivator or gti-devil;

thereby avoiding theexpense fof two machines, one for'listed crops andthe other Morev specifically Jtoi an ordinary wheeledv cultivatorlbyfthe clamps .provided yfoigholding theplows, and which 'has all-:of they funct'ons' .off v'lister corn xcultiv'atorV or go-devil.

A Figure 2 is a perspective View of lthe attachment per se, and i j Figure S-isa detail View of the attaching clamp.

' Four uprights or arms provided and lare adapted secured in the clamp 3 of.v the cultivator after the plows have been removed. The forwardarms 4- form supports for the usual tation along the rows.

may be used in all places wherethe go-devil or lister cultivator is employed and in addition it maybe equally well employed after the furrows are filled in to a level since this does not rely on a furrow improved machine go-devil for guidance asdoes the ordinary or lister cultivator.

Obioo viously, the machine as disclosed in Figure 1 y may be readily converted into a go-devilor n lister cultivatorby the ordinary farm hand Without the use of special tools; that such f converted machine has several advantages over the ordinary go-devil; and that the machine may with equal facility be reconverted into the conventional Wheeled cultivater.
